Hi, did you build it with a version based on our snapshot (2017-05-08) instead the latest one?

I mean it because we are a LTS distro, not a rolling release one. If we will upgrade crystal to the latest version (0.27.0); it will require upgrade some part of our entire environment (upgrade LLVM 4 to LLVM 6) by violating our packaging guidelines . I suggest you build a version based on our snapshot (2017-05-08) or request a LTS version for them since there are LTS distros such as Debian and Hyperbola using packages based on that date.
